Reissue of RFA-NS-18-019: Understanding the dynamic activity of neural circuits is central to the NIH BRAIN Initiative. The invention, proof-of-concept investigation, and optimization of new technologies through iterative feedback from end users are key components of the BRAIN Initiative. This FOA seeks applications to optimize existing or emerging technologies through iterative testing with end users. The technologies and approaches should have potential to address major challenges associated with recording and modulation (including various modalities for stimulation/activation, inhibition and manipulation) of cells (i.e., neuronal and non-neuronal) and networks to enable transformative understanding of dynamic signaling in the central nervous system (CNS). These technologies and approaches should have previously demonstrated their transformative potential through initial proof-of-concept testing and are now ready for accelerated refinement. In conjunction, the manufacturing techniques should be scalable towards sustainable, broad dissemination and user-friendly incorporation into regular neuroscience research. Proposed technologies should be compatible with experiments in behaving animals, validated under in vivo experimental conditions, and capable of reducing major barriers to conducting neurobiological experiments and making new discoveries about the CNS. Technologies may engage diverse types of signaling beyond neuronal electrical activity such as optical, electrical, magnetic, acoustic or genetic recording/manipulation. Applications that seek to integrate multiple approaches are encouraged. If suitable, applications are expected to integrate appropriate domains of expertise, including biological, chemical and physical sciences, engineering, computational modeling and statistical analysis.

The shock and kill strategy is one of the commonly used approaches for targeting latent reservoirs in hopes to cure HIV-1. It is based on the concept of purposely inducing reactivation of latent reservoirs in ART (antiretroviral therapy)-treated individuals by using stimulatory agents. However, it has become increasingly evident that attempts at elimination of HIV-1 reservoirs through latency reactivating agents (LRA) -mediated reactivation alone may not be sufficient. Novel strategies such as immunotherapy and gene excision therapies to optimize the recognition and elimination of reservoir cells such are being conceptualized and researched. Immunotherapy strategies like therapeutic vaccines to enhance HIV-1-specific CTL (cytotoxic T-cell) response, Chimeric Antigen Receptor T-cells (CAR-T cells) therapies, broadly neutralizing antibodies, dual-affinity retargeting antibodies that not only bind to HIV-1 viral envelope antigen but also activate the CTL response, and immune modulators, such as anti-PD1 (programmed cell death protein-1) or anti-CTL4 antibodies, to correct the immune exhaustion noticed in ART-treated individuals are being developed. In addition to immunotherapy strategies, Recombinant TALEN or CRISPR/Cas9 gene editing molecules delivered to latently infected cells designed to induce cleavage at highly conserved regions of the integrated HIV provirus genome are being researched. However, majority of immunotherapy-based and gene editing based HIV eradication strategies are focused on the periphery. The brain presents a unique challenge where access is difficult and innovative strategies are needed to overcome the blood brain barrier. It is also important to understand the potential CNS toxicity of immunotherapy-based and gene-editing based approaches currently being tested in clinical trials

This funding opportunity announcement (FOA) encourages applications for the Chronic, Non-Communicable Diseases and Disorders Across the Lifespan: Fogarty International Research Training Award (NCD-LIFESPAN) D43 program for institutional research training programs in low-and middle-income countries (LMICs, as defined by the World Bank classification system). Applications may be for collaborations between institutions in the U.S and an eligible LMIC or may involve just LMIC institutions if there is a previous track record of externally funded research and/or research training programs by the lead LMIC institution. The proposed institutional research training program is expected to sustainably strengthen the NCD research capacity of the LMIC institutions, and to train in-country experts to develop and conduct research on NCDs across the lifespan, with the long-range goal of developing and implementing evidence-based interventions relevant to their countries. The main focus of research training covered in the application must be relevant to the interests of at least one of the participating NIH ICs as stated by each in this FOA. Other NCD topics may be included as secondary and complementary focus areas. This Funding Opportunity Announcement (FOA) allows support of trainees as the lead investigator of an independent clinical trial; or a separate ancillary study to an existing trial; or to gain research experience in a clinical trial led by another investigator, as part of their research and career development.

The purpose of this Academic Research Enhancement Award (AREA) for Undergraduate-Focused Institutions is to support small scale research grants at institutions that do not receive substantial funding from the NIH, with an emphasis on providing biomedical research experiences primarily for undergraduate students, and enhancing the research environment at these applicant institutions. Eligible institutions must award baccalaureate science degrees, and have received less than 6 million dollars per year of NIH support (total costs) in 4 of the last 7 fiscal years.
